Monday’s Lou Dobbs Tonight on CNN gave attention to filmmaker Phelim McAleer – whose film Not Evil, Just Wrong premieres this Sunday and challenges Al Gore’s Inconvenient Truth – in the aftermath of his recent attempt to get Gore to respond to the British High Court ruling that there are nine factual errors in An Inconvenient Truth. But McAleer’s microphone was cut off as he tried to get Gore to answer for some of these inaccuracies and whether the former Vice President was trying to correct his mistakes. After a report by correspondent Casey Wian – who showed a clip of the exchange between McAleer and Gore, and who also mentioned some of the inaccurate points in An Inconvenient Truth about polar bears and Hurricane Katrina – Dobbs hosted a debate segment between McAleer and Fred Krupp of the Environmental Defense Fund.

McAleer pointed out that many of the environmental scientists pushing global warming theory were pushing global cooling theory decades earlier: "And the same environmentalists who are now saying it is warming, 20 and 30 years ago were saying we're going to have an ice age. I'm old enough to be at school and I was told that we're going into a new ice age."

This could be dismissed as anti-human - but the theory the environment can be saved by encouraging the use of birth control is one that has been popular with media some environmentalists. 

CNN's Lou Dobbs certainly hasn't shied away from the idea. On his Sept. 21 broadcast, Dobbs revisited an early report that the true path to environmental salvation wasn't by curbing greenhouse gas, but instead by subscribing to a Malthusian theory that slowing the growth of human population was the best path.

"We have more tonight on a story that we first brought to you last month, Dobbs said. "There is new evidence of the negative impact of overpopulation on our environment. The biggest threat to the environment isn't, it turns out, gas-guzzling cars or power plants but rather having too many children all around the world."
